Flashing PON light in 90% of cases means the ONT can see light but hasn't been provisioned on the network. So either Hey! have incorrect data for the OLT port that your address is on and are trying to provision it in the wrong place, their install team have plugged into someone else's CBT by mistake, or they just don't realise it needs provisioning and aren't doing that step. Should be very easy to fix if anybody with some competence gets involved.

Been with Hey for couple of months with a few notable downtimes ( put it down to new tech and early adopter risk).

But your experience has reinforced my view that the company is very fragmented with management who have no real idea how to organise support structures and struggle with basic trouble shooting .

My feeling on your issues as mentioned are most likely very easy fixes but the teams currently are not switched on enough to figure it out.

Engineer came today (same one as before) - again tried to provision with new ONT box but no luck- told him about this thread and what you said @jpm about someone else's CBT but he went and checked the HeyB box outside under the pavement and it only had one switch and only one connection coming off it which was mine. He was on chat with some Spanish dude and they couldn'figure it out as power levels were perfect. He then called a senior Engnieer and I overheard them saying it's probably because my road is not up and running yet. I asked him about this and said so it's like the pipes have been laid but they haven't switched on the water yet to my road- he said something something like that.
To be fair the Engineer was sympathetic and said it is a bit of mess with a management at the moment.

Anyways going to send an email to cancel over the weekend and even ask why I was offered it in the first place!

Makes no sense, the PON light is flashing so your road is hooked up to something.

Perhaps it's better that you're not relying on these people for your internet connection though.

Sent an email requesting how to cancel even though I am not activated- copied in CEO as well so she is aware of these operational issues. Copied in others sales emails I had alreday- let's see what happens and if they try claw back £££ from me!

Planned maintenance in my area last night (SL9) with an advertised outage of midnight->4am. Actual outage 30mins at approx 00:33until 01:02.

Credit where credit is due, no issues when the service came back and throughput and latency looking good.

A senior Engineer turned up today and diagnosed the problem! He was in the area and said he can pop by but didn't have an appointment but was intrigued by the problem- good initiative LOL.

He had to go the main junction box about 5 streets down after checking everything inside and on the main road and said all he did was plug the connection he saw coming through from my side (he shone a light down the other way) into another port and voila it is working! He mentioned the original port was faulty and he just picked the next one to it.

Getting about 950MB up and down directly through the router, but only about 250MB through my Mesh S4 Deco so will have to look at that at some point. Also did some torrenting whilst my son is online gaming and it is much faster than VM. (Mods please remove if not appropriate)

Now I have to decide whether to cancel or not as he said they haven't processed the cancellation yet but my emails have hit head office.

LOL now I'm torn as I'm like a kid in a candy shop. Will use for 14 days and check reliability doing the usual stuff and decide.

Ugh, I'm back to having evening peak time bandwidth issues again. For the last three evenings, downstream performance has been about 30Mb on a 1Gb connection. Seems to start at 6pm and get's really bad between 8pm & 11pm....then slowly improves up to midnight.

Raised with support and supplied WAN performance graphs.

Sorry to hear that!
Must be local issue or wan subnet-specific - no issues here (wan GW is 95.82.40.x)

Absolutely terrible performance here too.

My connection hasn't been "Perfect" since the huge issues we all had before.
Support is as always, less than useful.
